The chart is particularly interesting for our Friday group toons.
To get to level 13 the first lifer will need 20k XP less than before. The second lifer will need 30k MORE XP than before. The third lifer will need 81k MORE than before.

So my third lifer fighter lost 2 ranks and is barely into level 13. That means some of the third lifers that just made it into level 13 could have dropped back to level 12.
